Perhaps you should try some spelling variations:
decrease lesions » disease lesions (Expand search), decreased response (Expand search), decrease adhesion (Expand search)
lesions decrease » response decrease (Expand search), lesions case (Expand search)
decrease burden » disease burden (Expand search), decrease further (Expand search)
burden decrease » burden disease (Expand search), urea decrease (Expand search), burgers decreases (Expand search)
decrease split » decrease ipla2 (Expand search), decrease implicit (Expand search), decrease quality (Expand search)
split pattern » point pattern (Expand search), gait pattern (Expand search)

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease lesions decrease burden decrease ) OR ( decrease AND decrease split pattern ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease lesions decrease burden decrease ) OR ( decrease AND decrease split pattern ))*.
